Nickel catalyzed copolymerization of butadiene with silicon-, nitrogen-, sulfur-, oxygen-, boron-, and phosphorous-functionalized dienes exhibiting high regio- and stereocontrol, and a remarkably high comonomer incorporation into the formed copolymer will be reported. Decreasing overall polymerization rates in these copolymerizations are strongly correlated to increasing copolymerization parameters favoring functional comonomer- over butadiene incorporation. Steric modifications of the functionalized diene allow for the generation of gradient- or statistical copolymers by influencing copolymerization parameters. We will discuss a model rationalizing these observations.
